Electric Judgement

A stream of dark, crackling electricity arcs out toward a creature within range, forming a sustained bolt of lightning between you and the target. Make a ranged spell attack against that creature. On a hit, the target takes 1d6 lightning damage and on each of your turns for the duration, you can use your action to deal 1d6 lightning damage to the target automatically.
The spell ends if another action is taken, the target is ever outside the spell’s range or if it has total cover from you.

This spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6)
